Connecticut is a great state for home solar… for now. The state currently has a nice rebate program, and federal solar incentives and net metering are available, but the last two are set to change soon.
In 2019, the state legislature passed a bill to extend the state’s net metering law to all new solar owners who get their panels installed before the end of 2021. After that, going solar will be much less financially advantageous.
The big federal solar tax credit will also step down from 26% in 2020 to just 10% in 2022 before disappearing for home solar in 2023. The combination of the end of net metering and the impending death of the solar tax credit means now is the time for Connecticut homeowners to consider installing solar panels.
The average cost for an installed residential solar system in Connecticut is currently $12,676 after claiming the 26% federal solar tax credit. This is $2.86 per watt. However, there is some variance in solar prices in different parts of the state. The graph below shows the average cost of installed solar systems in your part of the state.

Solar panels have fallen in price by more than 80% in the last ten years. In 2020 they also remain subsidized by the 26% federal tax credit and the net metering law, making them an excellent investment. They offer a return well above the long term average return from both the share market and also property investment.
Another way to look at this question is the levelized amount you will pay for each kWh of power you will use over the next 25 years with and without solar panels. As you can see below the savings are significant.

The most significant incentive to install solar panels for homes and businesses is the federal solar tax credit. As mentioned above, the amount of the credit will decrease from 26% to 22% of the cost of the solar installation at the end of 2020. Because home and business owners want to get the largest incentive amount possible, solar panel installation companies will likely be flooded with new projects before year’s end. In order to maximize your savings potential, the best time to go solar in Connecticut is now.
Connecticut is home to some of the highest utility rates in the US, and the current net metering law means you’ll get full credit for every kilowatt-hour your solar panels produce. When the sun is high in the sky, your panels produce more electricity than you use. Net metering means you get credit for that excess energy that you cash in when you need electricity at night when your panels aren’t producing. Remember, net metering in Connecticut will only be offered to people who install solar panels before 2022.
Connecticut itself offers the Expected Performance-Based Buydown Incentive program, which is a cash payment based on system size, and reduces the up-front cost of going solar.
Additionally, the Constitution State offers solar sales and property tax exemptions to reduce the up-front and long-term cost of going solar.

Solar panels power your house when they can but your home uses the utility company for power at other times. In 2022 "solar systems with battery storage" are becoming more popular. These are known as hybrid systems.
A grid-tied system is the most common type of solar system. It has no solar battery for backup power and utilizes net metering to maximize savings. Solar panels are mounted on your roof then wired together, and the power generated flows into an inverter where direct current (DC) electricity is converted into alternating current (AC) electricity. This electricity is either used by your home or is exported to the utility grid.
In hybrid solar systems, rooftop solar panels are connected to both a solar battery and the electric grid. The solar electricity generated by your panels that your home does not use is stored in the battery instead of being sent to the grid, which reduces your reliance on the utility while also providing backup power when needed. Battery storage is still expensive but you may be able to reduce costs by using state incentives.
Off-grid solar systems are not connected to the grid at all, so all of your energy needs must be met by the sun. There is no utility to fall back on. The solar installation needs to power your home not only during the day, but after dark as well, so many solar panels and a large battery system are required. These systems are often expensive and don’t make sense for homes that have access to the grid.

No, but cleaning them can improve power generation if they are dirty.
Given this environment, and the effect of import tariffs placed on solar panels by the Trump administration during 2018, it is hard to see that solar power system prices in Connecticut will fall during 2022.
Depending on the location, solar panels will generate different amounts of electricity.
A solar system that is installed on a south-facing 31-degree pitch roof Connecticut will generate 1,153kWh of peak DC (direct current) capacity per year per 1kW in Connecticut.

The advantages of installing solar panels in Connecticut are that there are both state-based incentives and the federal tax credit available. In addition, Connecticut also has expensive utility rates which makes the overall return on investment for an installation of residential solar panels in the state one of the best in the nation.
The disadvantage of installing solar panels for your home in Connecticut is that there is less overall solar irradiation per year. So, a solar system produces less in Connecticut than it would in sunnier states, like Arizona.
However, the local and federal incentives more than make up for the limited sunshine in the state.
